TAG: RINEX

The next version (0.93) of the “gfzrnx” RINEX-2/3 Tool is now available. Because of user feedback, the developers have fixed bugs and have added these new features: strict epoch interval handling via -sei command line parameter support of the upcoming RINEX version 3.03 (BDS B1 obs. types, IRNSS support) The software is still in a beta state, according to the GFZ IGS... read more

Synthetic-Aperture GNSS Signal ProcessingWe take a look at a novel GNSS signal-processing technique, which uses the principles of SAR to improve code and carrier-phase observations in degraded environments such as under forest canopy. The technique can simultaneously reject multipath signals while maximizing the direct line-of-sight signal power from a satellite. Along with a specially programmed software receiver, it uses either a single conventional antenna mounted, say, on a pedestrian’s backpack for GIS applications or a special rotating antenna for high-accuracy surveying.
